What are EPAs? The entrustable professional activity (EPA) concept allows faculty to make competency-based decisions on the level of supervision required by trainees. Competency-based education targets standardized levels of proficiency to guarantee that all learners have a sufficient level of proficiency at the completion of training.

Trust is a central concept for safe and effective health care. Patients must trust their physicians, and health care providers must trust each other in a highly interdependent health care system. In teaching settings, supervisors decide when and for what tasks they entrust trainees to assume clinical responsibilities. Building on this concept, EPAs are units of professional practice, defined as tasks or responsibilities to be entrusted to the unsupervised execution by a trainee once he or she has attained sufficient specific competence. EPAs are independently executable, observable, and measurable in their process and outcome, and therefore, suitable for entrustment decisions. Sequencing EPAs of increasing difficulty, risk, or sophistication can serve as a backbone for graduate medical education.
